Quark confinement due to creation of micro AdS black holes in quarkonium model

TL;DR

This paper explores how a large negative cosmological constant in AdS space can explain quark confinement by inducing a linear potential, potentially linked to micro black holes formed in high-energy collisions.

Contribution

It demonstrates that the geometry of AdS space with a large negative cosmological constant can naturally produce quark confinement effects in the quarkonium model.

Findings

Large negative cosmological constant leads to a linear confining potential.

The geometrical features of AdS space explain quark confinement.

Micro black holes in hadronic collisions may justify the large cosmological constant.

Abstract

We use the solution of the Dirac equation for quarkonium atom in the 4D Anti de sitter (AdS$_{4}$) space to investigate the effect of the large negative cosmological constant on the phenomenon of quark confinement. We do the required calculations in the AdS$_{4}$ space to indicate that large cosmological constant can describe the quark confinement. In fact using the coulomb potential in Dirac equation while we employ the AdS metric will additionally lead us to a linear potential in the quark-antiquark interaction which can be considered to explain the quark confinement. This confining term is arising essentially from the geometrical features of the space. On the other hand the origin of the large cosmological constant can be justified by assuming the appearance of micro black holes in the recent hadronic collision process which is now current, for instance, at the LHC project.
